When THR spoke with executive producer Shawn Levy, he revealed the new season will feature at least three new characters:

There’s definitely a handful of really compelling new characters this season, but absolutely servicing the core group first and foremost. Like the show itself, it’s multigenerational new characters and really, really intriguing ones.”

Here’s the new character descriptions from THR:

Max is a tough and confident 13-year-old female whose appearance, behavior and pursuits are more typical of boys than of girls in the era. She has a complicated history and a difficult relationship with her stepbrother, Billy, that’s made her protective of her past and generally suspicious of those around her. She’s also good on a skateboard, which she uses to get around pretty much everywhere.

Billy is a super muscular, overconfident 17-year-old. He’s so captivating and edgy that there are rumors flying around that he killed someone at a school he attended in the past. Billy steals peoples’ girlfriends, is a drinking-game pro and drives a black Camaro. But his violent and unpredictable nature shows itself to those closest to him, especially to ones who are younger than he is.

Roman, meanwhile, is described as a male or a female of any ethnicity between the ages of 30 and 38. After growing up homeless with a drug-addicted mother, he or she suffered a great loss at an early age and has been seeking revenge ever since. Roman is ultimately an outsider who doesn’t understand how to connect with people.
